Procedure

To a solution of tert-butyl [2-(4-bromophenyl)ethyl]-[(2R)-2-phenyl-2-(tetrahydro-2H-pyran-2-yloxy)ethyl]-carbamate (620 mg) in 1,2-dimethoxyethane (7 ml) were added [3-(cyclohexyloxy)-4-(methoxycarbonyl)phenyl]boronic acid (410 mg), tetrakis(triphenylphosphine)palladium (99 mg) and aqueous solution of sodium carbonate (2M, 1.35 ml), and the mixture was stirred at 75° C. for 5 hours under nitrogen. The mixture was diluted with ethyl acetate and water. The organic layer was separated, washed with brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=9/1) to give methyl 4′-[2-[(tert-butoxycarbonyl)[(2R)-2-phenyl-2-(tetrahydro-2H-pyran-2-yloxy)ethyl]amino]ethyl]-3-(cyclohexyloxy)-4-biphenylcarboxylate (672 mg).
